1 Photosynthesis and Respiration
Cellular Energy Photosynthesis and Respiration

2 Autotrophs--Photosynthesis
Takes light energy and converts into food Reactants Products

3 Photosynthesis Formula
6 CO 6 H2O C6H12O6 + 6 O2 O2 CO2 Sugar Green plants use the energy of sunlight to convert carbon dioxide and water into high-energy sugars and oxygen

Water CO2 Carbon Dioxide HIGH NUMBER OF CHLOROPLASTS = PHOTOSYNTHETIC ORGANISM!!! Light dependent Chloroplast w/pigment chlorophyll O2 C6H12O6 GLUCOSE

5 Chemical energy and ATP
ATP (Adeonsine Tri-Phosphate) Is the principal component that cells use to store and release ENERGY when its broken down Adenine Ribose 3 Phosphate groups

6 Where does ATP come from???

7 Cellular Respiration Cell respiration is the breaking down of glucose and other food molecules in order to release energy, in the form of ATP Food Energy

8 Respiration vs. Photosynthesis
Respiration is the reverse reaction of photosynthesis

9 Cell Respiration Formula
C6H12O6 + 6 O2 6 CO 6 H2O O2 CO2 Sugar

10 Two Types of Cellular Respiration Review
Anaerobic Respiration Aerobic Respiration Can only occur in the presence of oxygen Produces water and carbon dioxide Generates 36 ATP!!! Occurs without the use of oxygen Produces lactic acid or alcohol and carbon dioxide Generates only 2 ATP So….which one is more efficient???
